Merriweather was designed by the world renowned architect Frank Gehry, who is best known for defying architectural conventions. In the early 1960’s, he accepted the challenge of developing a design that would least disturb the natural topography of the Merriweather site. He succeeded and the pavilion opened in 1967. Its acoustics were considered by many in the industry to be the best among outdoor venues.10475 Little Patuxent ParkwayColumbia, MD 21044Information 410.715.5550

As a baseball park, RFK Stadium is unique in having only an upper deck across the outfield, atop a high wall. Burly slugger Frank Howard hit a number of tape-measure home runs in his career, a few of which landed in the center field area of that upper deck; the seats Howard hit with his home runs are painted white, rather than the yellow of the rest of the upper deck.
